Implementation of a Custom Genil Model to Create

Component in Web UI inShare

Created a custom GenIL object model to create and save BOL objects. To use that custom GenIL component to create and save the data in database.

1.> Open a Transaction BSP_WD_CMPWB .

2.> Enter Component name as ZCUST_CMP and click on create

3.> Right Click on Model -> Add Model

4.> Add Component Set name as ZCSET_CUST which you had created while creating Genil Model.

5.> You can see the Component Structure Browser , expanding Model will show your

Root Object Customer , Key Structure , Attribute Structure.

6.> Create a Custom Controller named as ZCuCo so that later on you can navigate or pass the

data between views.

7.> Add Customer as a Model Node and a BOL entity -> Click on Next till Complete.

8.> Double click on custom controller , you can see list of attributes of a context node you added.

9.> Right Click on View and Create Over View Page name as OverViewPage .

10.> Create a New View using Create -> Define Name as CreateCustomer.

11.> Add Model Node and BOL entity as Customer and Bind it with Custom Controller.

12.> Select a View Type form View as required and Click on Complete.

13.> Click on Configuration Tab and Add the Available fields.

14.> Here you can change the field Properties using Hold down ALT+Field.

15.> Next Step is assignment of View to OverViewPage.

16.> then Assign OverViewPage to Windows

17.> Next Step is about to add View to Display assignment blocks of OverViewPage.

18.> Click on Test Button.

19.> Here the fields are not bounded , to achieve this a custom bol objects and created a custom

genil class,

then first you have to laod that bol object and a component set , you can use this code

inDo_init_context method

so that initially when you run crm_ui , it will initailizes the component set and bol

objects.

Instead of Initialization in Do_init_context , Lets create a button Create (to Load bol Objects) and

and Save to update in database (ZMast_Cust).

20.> Declare a global attribute GT_BUTTONS in a implementation class.

21.> Click on Page Attributes and add the following code for BSP Page.

<%@page language="abap" %> <%@extension name="chtmlb" prefix="chtmlb" %>

<%@extension name="thtmlb" prefix="thtmlb" %> <%@extension name="uhtmlb" prefix="uhtmlb" %>

<%

DATA lv_xml TYPE string. lv_xml = controller->configuration_descr->get_config_data( ). %>

<chtmlb:config xml = "<%= lv_xml %>"

mode = "RUNTIME" /> <uhtmlb:toolbar id = "Toolbar"

buttons = "<%= controller->gt_buttons %>" maxButtonNumber = "3" />

22.> Redefine Do_init_context method and add the code to trigger events on button.

DATA : lr_entity TYPE REF TO cl_crm_bol_entity,

lv_collection TYPE REF TO if_bol_bo_col.

* Define Buttons

DATA ls_button TYPE crmt_thtmlb_button.

REFRESH gt_buttons.

ls_button-id = 'Create'.

ls_button-text = 'Create'.

ls_button-on_click = 'Create'. ls_button-enabled = abap_true.

ls_button-type = cl_thtmlb_util=>gc_icon_create.

APPEND ls_button TO gt_buttons.

ls_button-id = 'Save'.

ls_button-text = 'Save'.

ls_button-on_click = 'Save'.

ls_button-enabled = abap_true.

ls_button-type = cl_thtmlb_util=>gc_icon_save. APPEND ls_button TO gt_buttons.

ENDMETHOD.
